l
Always be careful when skidding or sliding.
Learn to safely control skidding or sliding
by practicing at low speeds and on level,
smooth terrain. On extremely slippery sur-
faces, such as ice, go slowly and be very
cautious in order to reduce the chance of
skidding or sliding out of control.
l
Never operate an ATV in fast flowing water
or in water deeper than that recommended
in this manual. Remember that wet brakes
may have reduced stopping ability. Test
your brakes after leaving water. If neces-
sary, apply them several times to let friction
dry out the linings.
l
Always be sure there are no obstacles or
people behind you when you operate in re-
verse. When it is safe to proceed in reverse,
go slowly.
l
Always use the size and type tires specified
in this manual.
l
Always maintain proper tire pressure as de-
scribed in this manual.

distilled water if refilling is necessary. (See
pages 8-73 ~ 8-79.)

Tires
Always use the recommended tires.
WARNING
Use of improper tires on this ATV, or opera-
tion of this ATV with improper or uneven tire
pressure, may cause loss of control, increasing
your risk of accident.
Pay attention to the following.
1. The tires listed below have been ap-
proved by Yamaha Motor Co., Ltd. for this
model. Other tire combinations are not
recommended.

2. The tires should be set to the recom-
mended pressure:l
Recommended tire pressure
Front 25 kPa (0.25 kg/cm
2, 0.25 bar)
Rear 25 kPa (0.25 kg/cm2, 0.25 bar)
l
Check and adjust tire pressures when the
tires are cold.

l
Tire pressures must be equal on both sides.
3. Tire pressure below the minimum speci-
fied could cause the tire to dislodge from
the rim under severe riding conditions.
The following are minimums:
Front 22 kPa (0.22 kg/cm
2, 0.22 bar)
Rear 22 kPa (0.22 kg/cm2, 0.22 bar)
4. Use no more than the following pressures
when seating the tire beads.
Front 250 kPa (2.5 kg/cm2, 2.5 bar)
Rear 250 kPa (2.5 kg/cm2, 2.5 bar)
Higher pressures may cause the tire to
burst. Inflate the tires very slowly and
carefully. Fast inflation could cause the
tire to burst.

How to measure tire pressure
Use the low-pressure tire gauge.NOTE:The low-pressure tire gauge is included as
standard equipment. Make two measurements
of the tire pressure and use the second read-
ing. Dust or dirt in the gauge could cause thefirst reading to be incorrect.
Set pressure with tires cold.
Set tire pressures to the following specifica-
tions:

skills or the conditions.WARNING
Always go at a speed that is proper for the ter-
rain, visibility and operating conditions, and
your experience. Operating this ATV at speeds

Owner’s manual and tool kit
You are recommended to put this owner’s
manual and low-pressure tire gauge in the vi-
nyl bag and always carry them along with the
owner’s tool kit under the seat. The service in-
formation included in this manual is intended
to provide you, the owner, with the necessary
information for completing your own preven-
tive maintenance and minor repairs. The tools
provided in the Owner’s tool kit are sufficient
for this purpose, except that a torque wrench is
also necessary to properly tighten nuts and
bolts.
NOTE:

If you do not have a torque wrench available
during a service operation requiring one, take
your machine to a Yamaha dealer to check the
torque settings and adjust them as necessary.
